HID Xenon Fuse Relay Wire Harness With Resistor Kit

  • Protects your HID system by drawing stable current directly from your battery

  • No more flickering due to low electrical current

  • 40 Amp relay and 30 Amp fuse

  • High Quality materials for maximum durability and performance

  • One relay harness powers both driver and passenger sides

  • Designed to fix any HID flickering problem. Will fix most HID problem like Dodge vehicles.
  • Why do you need relay harness?

    The primary function of an automotive headlight wire harness is to provide power directly from the vehicles battery to the lighting system. This allows the bulb, or HID ballast, to operate independently of the vehicles original wiring system and can provide a power source that is more consistent.

    Problem: Delayed Start

    An HID Ballast requires more power to ignite on start-up than during normal usage. This initial power surge can sometimes be problematic for vehicles with weaker electrical systems that cannot provide the power needed. The vehicles stock headlight connectors are not capable of providing 7-8 amps per headlight and as a result, only one HID turns on when the switch is turned on. After about 20 seconds when the ballasts power consumption drops to 3.2 amps, you can quickly turn the lights off then back on and voila, both HID lights turn on. This scenario happens all the time and is the direct result of insufficient power.


    An HID wiring harness with power supplied directly from the battery would eliminate this issue as it would be able to consume up to 30 amps through the batteries positive terminal to ignite both ballasts.

    Problem: Flickering

    An HID Ballast that is not getting sufficient power from a stock headlight connector will cycle on and off as it tries to ignite and power on. This can also be a result of an inefficient ballast that is not able to convert the available power to properly ignite an HID system.


    An HID wiring harness will provide the power necessary to ignite even an inefficient ballast for flicker free HID lighting.

    Problem: Dim/Dark Light Output:

    When a ballast is under-performing, light output can appear more blue and dimmer than it should be. This is a result of the ballast not converting enough power to ignite the bulb at its optimal range. A bulb that is 4300K connected to a ballast with a weak power source, can look like an 8000K blue color with substantially lower light output.


    An HID Wiring harness will be able to provide more power to the ballast allowing the system to operate at 100%. This however is not a guaranteed solution as a poor quality ballast which will not output sufficient power no matter how much is being inputted.

    Problem: Uneven Brightness

    My passenger side is brighter than my driver side! Power in not always delivered in equal amounts to each headlight, and depending on your vehicles wiring configuration, can have a negative impact on lighting performance when installing HIDs. If one headlight has less resistance to the power source i.e. length of wiring, fuse panels bridging connections etc, it will receive power first leaving less for the second headlight to consume. In this scenario, one headlight could end up being brighter than the other, or powering up to full brightness faster than the other.


    An HID wiring relay harness will provide equal amounts of power to each HID Ballast allowing for even and consistent brightness between both headlights.
